Let's Hear What Our

Customers Say

Great ride, super cool!
I'm very happy with the incredible electric assist and optimal braking. I also really like the LED lighting on the headlight and tail light, they are really, really, really efficient.
The e-bike is sleek, unique and has a really cool texture. Whenever I go out for a ride, I always get a lot of people asking me about my e-bike. I really love it. 
Excellent value for money
This is my second e-bike from this shop, the first was an M900, a little more expensive than this M520.
It was well packed and easy to assemble. It is sturdy and the materials are of good quality.
The battery has plenty of power and the bike comes fully equipped as standard: front + rear headlights, luggage rack, adjustable front suspension, comfortable saddle and good quality tyres.
The engine is very good, with strong and consistent thrust, and downshifting without jolts and sudden decelerations.

How many calories are burnt while cycling?
Once your fitness level has improved, complete at least 30 minutes of biking every day. According to Harvard Health Publishing, a 70-KG person can burn 446 calories in just 30 minutes cycling at a speed of 16 to 19 mph; burning excess calories leads to weight loss.
How can I try the bike before I buy it?
Currently we only support some cities to try before buying. Compared with Munich, Germany, we are opening trials in more regions.
Don't worry, if the electric bike is not satisfied, we support 14 days return
